Abstract
The invention discloses a rubber extruder, which comprises a body and a drive screw arranged in the body. A barrel fixed with the body is arranged between the body and the drive screw; the outer circumferential surface of the barrel is matched with the inner wall of the body; the drive screw is rotationally arranged in an inner hole of the barrel; a spiral water flow cavity for cooling water to flow is formed between the outer circumference of the barrel and the inner wall of the body; and correspondingly, the body is provided with a water inlet and a water outlet respectively communicated with the front end and the rear end of the water flow cavity. The cooling water cavity is designed to have a spiral shape, so that the cooling water circularly flows; moreover, the cooling water cavity is close to a rubber melt, so that problems that the conventional rubber extruder has lower heat exchange rate and non-ideal cooling effect on the rubber melt in the using process are solved, and the product quality is improved and stabilized.
Description
Technical field
The present invention relates to the extruder technology field, especially a kind of Rubber Extruder.
Background technology
Many extruders that are used for rubber production, in the course of the work owing to the extruder temperature that is used for extruded material is higher, can cause rubber melt too early fusion, cross thermal decomposition, therefore generally all be provided with cooling water channel to reach the purpose of temperature control at metering section in the transportation section, cooling screw in extrusion, reduce extruder temperature, make the rubber melt temperature satisfy instructions for use, thereby improve Solid Conveying and Melting efficient, stablize extrusion, improve quality of item.The present form that is provided with of cooling water channel on screw extruder, normally upwards offering several cavitys fuselage week as cooling water cavity, after adding cooling water screw rod and rubber melt are cooled off, the cooling water channel of this form is made cumbersome on fuselage, and flow of cooling water is relatively poor, need often to change, water channel is owing to be arranged on the fuselage still more, and is far away from the rubber melt distance, cooling effect is not ideal, and rate of heat exchange is lower.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in the prior art, a kind of Rubber Extruder be provided, solve existing Rubber Extruder in use rate of heat exchange lower, to the less-than-ideal problem of rubber melt cooling effect.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Rubber Extruder, comprise fuselage and be arranged on the interior drive screw of fuselage, be provided with between fuselage and the drive screw and the fixing machine barrel of fuselage, the machine barrel outer peripheral face matches with the fuselage inwall, drive screw turns is arranged in the endoporus of machine barrel, the current cavity that has helical form, confession flow of cooling water between machine barrel periphery and the fuselage inwall, correspondingly, on fuselage, offer inlet opening and the apopore that is connected respectively with the front-end and back-end of current cavity.
Specifically, described machine barrel periphery has a plurality of spiral helicine fins that are connected to, and space segment and fuselage inwall between adjacent two fins form described current cavity.
The invention has the beneficial effects as follows: the present invention is designed to spirality with cooling water cavity, in making cooling water be in constantly to circulate, simultaneously, cooling water cavity is near apart from rubber melt, thereby improved heat exchanger effectiveness effectively, prevented rubber melt too early fusion, stabilized product quality in the transportation section.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
1. fuselages, 2. drive screws, 3. machine barrels, 31. fins, 4. current cavitys, 5. inlet openings, 6. apopores among the figure
The specific embodiment
The present invention is further illustrated with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of Rubber Extruder as shown in Figure 1, comprise fuselage 1 and the drive screw 2 that is arranged in the fuselage 1, be provided with machine barrel 3 between fuselage 1 and the drive screw 2, machine barrel 3 fixes with fuselage 1, the outer peripheral face of machine barrel 3 contacts cooperation with the inwall of fuselage 1, drive screw 2 rotates and is arranged in the endoporus of machine barrel 3, on machine barrel 3 peripheries, have a plurality of continuous fins 31, the fin 31 that links to each other is shape in the shape of a spiral, space segment between adjacent two fins 31 and fuselage 1 inwall form the current cavity 4 for flow of cooling water, correspondingly, on fuselage 1, offer inlet opening 5 and the apopore 6 that is connected respectively with the front-end and back-end of current cavity 4.
The present invention in use, cooling water 5 enters spiral helicine current cavity 4 from the inlet opening, make helical flow around drive screw 2, discharge from apopore 6, simultaneously spiral helicine current cavity 4 is because from the rubber melt close together, like this, during the cooling water that feeds is in and constantly circulates, drive screw 2 and rubber melt are carried out adjustment control, therefore, the temperature of stabilized driving screw rod 2 and rubber melt effectively, improve heat exchanger effectiveness, prevent rubber melt too early fusion, improve Solid Conveying and Melting efficient, stablize the purpose of extrusion and raising quality of item thereby reach in the transportation section.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
